Overcoming Multidrug Resistance In Acute Lymphoblastic Leukemia Cells
Acute lymphoblastic leukemia (ALL) most commonly affects children, in whom there is an overall cure rate of 85%. A strong predictor of poor outcome is resistance to chemotherapy with glucocorticoids. Such resistance is caused, at least in part, by an inability of the leukemic cells to die by a process known as mitochondrial apoptosis...

Genome Study Shows How Strep Throat Germ Circumvents Our Immune System
Investigators at The Methodist Hospital Research Institute in Houston examined for the first time the long-term response to strep throat on a genome-wide level, shedding light on how group A streptococcus interacts with the patient's immune system and attempts to circumvent it. Results were published in the Proceedings of the National Academy of Sciences (PNAS)...
Hospital-Acquired Infections, MRSA, Killed 48,000 Americans In One Year
According to a new study, sepsis and pneumonia, two common conditions caused by hospital-aquired infections like MRSA, killed 48,000 Americans in 2006, and cost the nation over 8 billion dollars to treat...
VARI Findings May Help Patients With Deadly Kidney Cancer
Van Andel Research Institute (VARI) researchers have found a way to reverse resistance to sunitinib, a treatment that is currently the first line of defense against clear cell renal cell carcinoma (ccRCC), a deadly form of kidney cancer. Most patients who show a positive response to sunitinib develop a resistance to the drug after one year of treatment...
Key To Antibiotic Resistance Is To Leave No Enemies Behind, Says Expert
A new paper in the February 17th edition of the journal Molecular Cell describes how exposure to low levels of antibiotics increases mutations in E. coli and Staphylococcus bacteria hundreds of times more than normal, making the creation of drug-resistant strains more likely...
Chemical Found In Feverfew Shuts Down Pro-Survival Signal In Resistant Breast Cancer Cells
Combining tamoxifen, the world's most prescribed breast cancer agent, with a compound found in the flowering plant feverfew may prevent initial or future resistance to the drug, say researchers at Georgetown Lombardi Comprehensive Cancer Center. The finding, reported online Feb...
Team Develops New Weapon To Fight Disease-Causing Bacteria, Malaria
Researchers report that they have discovered - and now know how to exploit - an unusual chemical reaction mechanism that allows malaria parasites and many disease-causing bacteria to survive. The research team, from the University of Illinois, also has developed the first potent inhibitor of this chemical reaction. The findings appear in the Proceedings of the National Academy of Sciences...
Antibiotics As Active Mutagens In The Emergence Of Multidrug Resistance
Multidrug resistant bacteria such as Methicillin-resistant Staphylococcus aureus (MRSA) pose a major problem for patients, doctors, and the pharmaceutical industry. To combat such bacteria, it is critical to understand how resistance is developed in the first place...
Low Levels Of Antibiotics Cause Multidrug Resistance In 'Superbugs'
For years, doctors have warned patients to finish their antibiotic prescriptions or risk a renewed infection by a "superbug" that can mount a more powerful defense against the same drug...
One-Third Of Antimalarial Medicines Sampled In 3 African Nations Found To Be Substandard
The first results from a large-scale study of key antimalarial medicines in ten Sub-Saharan African countries reveal that a high percentage of medicines circulating on national markets are of substandard quality and thus may contribute to the growth of drug-resistant strains of Plasmodium falciparum, the most virulent form of malaria...
Findings Of Poor Quality Malaria Drugs In Africa Add To Artemisinin-Resistance Worries
A study released on Monday found that between 26 percent and 44 percent of artemisinin-based malaria drugs sold in Madagascar, Senegal and Uganda "failed quality testing" because of impurities or insufficient amounts of active ingredient, the Associated Press reports. The study, which was conducted by the nongovernmental U.S...

Proteomics Study Reveals A Protein That, When Suppressed, Makes Cancers More Susceptible To Chemotherapy
Taxanes, a group of cancer drugs that includes paclitaxel (Taxol®) and docetaxel (Taxotere®), have become front-line therapy for a variety of metastatic cancers. But as with many chemotherapy agents, resistance can develop, a frequent problem in breast, ovarian, prostate and other cancers...

Researchers at the University of Illinois at Chicago and Israel's Weizman Institute of Science have found that two antibiotics working together might be more effective in fighting pathogenic bacteria than either drug on its own...
Evolution And Spread Of Drug-Resistant Bacteria Tracked Across Hospitals And Continents
An international team of researchers has used high resolution genome sequencing to track a particularly virulent strain of MRSA as it traveled between South America, Europe and Southeast Asia.
